Modernization isn’t one-size-fits-all.
Some challenges stand alone. Others are deeply connected. Whether you’re modernizing applications, data, mainframes or all three, we tailor the approach to your business by combining strategy, engineering, and change to drive real progress. We’ve done this across industries, tech stacks, and levels of complexity, and we’re ready to meet you where you are.
Rebuild without regret
Application modernization
Your applications weren’t built for what your business needs now or where it’s going next. Slalom helps untangle the monolith and modernize with precision, turning rigid architectures into modular, scalable systems that eliminate work-arounds and slowdowns—giving your teams a clean foundation to build on with confidence.
Give data a new day
Data modernization
Your data is doing the work, but your platform is holding it back. Slalom supports the modernization of your data stack with scalable, AI-ready infrastructure that can help reduce cost, improve trust, and unlock near real-time insight—clearing the path for clean, connected data that drives your business forward.
Retire with respect
Mainframe modernization
Your mainframe earned its place. Now it’s time to replace it with something built for what’s next. Slalom helps you transition critical workloads with AI-assisted tools and a phased, low-risk approach. What stays: your business logic and reliability. What goes: the cost, complexity, and talent risk. It’s not disruption—it’s a respectful rebuild for scale and speed.
